Answer:

The value of x are x=2\sqrt3 i,-2\sqrt3 i

Step-by-step explanation:

Given : Function f(x)=13x^2+156

To find : The value of x?

Solution :

To find the value of x we equation the function to 0,

i.e. f(x)=0

13x^2+156=0

Subtract 156 both side,

13x^2=-156

Divide by 13 both side,

x^2=-\frac{156}{13}

x^2=-12

Squaring both side,

\sqrt{x^2}=\sqrt{-12}

x=\pm 2\sqrt3 i

Therefore, The value of x are x=2\sqrt3 i,-2\sqrt3 i

Simplifying
f(x) = 13x2 + 156

Multiply f * x
fx = 13x2 + 156

Reorder the terms:
fx = 156 + 13x2

Solving
fx = 156 + 13x2

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.
f = 156x-1 + 13x

Alan says that two lines in the coordinate plane are perpendicular if and only if the slopes of the lines are m and 1m. Identify
mart [117]

Answer:

First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)

That is the first error of Alan.

Now, there is another error.

If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).

But we can not really divide by zero, so we should state that:

m can not be zero, if a line is horizontal, the perpendicular line must be vertical.
